Weathering and erosion played a big role in forming the grand canyon. The rock was being weathered, most likely mechanical weathering, and then it eroded away. Think of a pebble that is in running water. When you pick it up, it is smooth, right. But before, it was pointy. So, the grand canyon was once a big rock, and weathering broke through it making it one of the wonders of the USA.
Species are single organisms that are able to reproduce, while a population is a group of species living in the same general area.
Answer:
Muscle contraction is an example of mechanical contraction.
Explanation:
Muscular contraction is the activation of generating tension which appear in the muscle fiber as it does't change the length of muscle and is followed by muscular relaxation.
Muscle contraction is based on force and length.
The process of skeletal muscle contraction is an energy requiring process.
In order to perform mechanical work,actin and myosin utilizes the chemical energy into ATP that ultimately require during muscle contraction and relaxation.
In a working muscle,glucose is released from glycogen that are stored in the muscle by the process of glycolysis in which glucose broken down into ATP that is required by cells and tissues.

1ml of milk = 1g
of milk<span>
and in 1 gram of whole milk, there is only one
calories
and in whole milk the percentage of milk
fat is 3.25%</span>
To get the percentage of milk fat, divide the
grams of fat present in milk by the total weight of milk and then multiply by
100.
<span>There are many
types of milk, like skimmed milk, low fat milk, partly skimmed, raw milk, whole
milk etc. in all these types the percentage of milk fat is different.</span>
